🕵️ Our Research
This section of the guide shares everything you need to know about the under-sink water filtration systems for well water, including the types of under-sink water filters available, which common well water contaminants can be tackled by under-sink filters, who should buy an under-sink system, and more.
🤔 What are the Common Well Water Contaminants?
According to the EPA, the most common categories of well water contaminants are:
- Microorganisms – Like bacteria, viruses, and parasites
- Nitrate and nitrite
- Heavy metals – Like lead, arsenic, copper, selenium, and chromium
- Radionuclides – Like radium and uranium
- Organic chemicals – Like pharmaceuticals, pesticides, and solvents
Most of these contaminants enter well water through surface runoff or from seeping through the soil into the aquifer. Some well water impurities occur naturally in the environment, while others are caused by industrial and agricultural pollution, or poor waste disposal.
We assume you know quite a lot about well water contamination if you’re reading this guide, but if you are looking for more information on the subject, check out this guide.
🚰 Do I Need a Water Filter That Removes Well Water Contaminants?
If you have a private well, your water doesn’t get treated by your local authority, so it’s delivered to your home in a raw, untreated form.
That means you do need to treat your water before you can use it, and an under-sink water filter for well water will be hugely beneficial to you.
Alongside an under-sink filtration system, you might also need a form of pre-treatment, like a sediment filter or a water softener, depending on your water quality and what type of filter you buy.

🧪 How We Tested
Our original testing process involved carrying out before-and-after water tests with Tap Score laboratory testing. However, it quickly became apparent that our own well water was pretty mild compared to the test waters used in official industry testing. We realized that our results were limited, and didn’t tell us much about a filter’s true capabilities.
For this reason, our testing now focuses solely on the user-friendliness of an under-sink filtration system, and how it performs on a day-to-day basis. We combine our invaluable real-life user experience with official testing data from the NSF, the WQA, and third-party testing organizations. This gives us the best understanding of how different filters compare across the board.
📊 How We Chose
This guide is solely for under-sink water filter systems that are capable of removing well water contaminants. Because of this, our search was fairly focused, and we had a relatively small pool of products to compare.
We chose the filters on this list based on their ability to remove common well water contaminants, the quality of their components, their customer feedback, and their value for money.
Contaminant Removal Abilities
First and foremost, we know that if you’re looking for an under-sink water filter system for well water, you expect it to remove the common contaminants in your well water supply.
We began our research with a list of the common well water contaminants, as defined by the EPA, and looked at product descriptions and test results (and, if information wasn’t available, spoke directly to manufacturers) to tick these contaminants off our list. The filters that removed the most contaminants made it into our group of shortlisted products.
Component Quality & Durability
We understand that there’s nothing worse than buying a so-called durable water filter system that lets you down after less than a year of use. That’s why testing our shortlisted filters was so important to us.
We didn’t want to take the manufacturer’s word for it; we wanted to see with our own eyes and feel with our own hands to confirm that a water filter was good-quality and built to last. We also read customer reviews to learn about a filter’s long-term durability.
This helped us to narrow down our choices, eliminating the products that didn’t meet our expectations.
Customer feedback is an invaluable tool when you’re researching the best water filter systems. From reading hundreds of customer reviews, we were able to compare the overall user experience for all our shortlisted under-sink water filters.
Customer feedback gives a clear impression of how a water filter lives up to customer standards and expectations. We avoided the under-sink water filters that received repeatedly negative criticism for the same reasons, such as poor-quality design or subpar filtration.
Value for Money
Value for money was perhaps our most important consideration of all when choosing under-sink well water filters, as it combines all the most important features of a water filter and answers the question: “Is it worth the price we’re paying?”
We know that customers work hard to earn their money, and they want to be certain that they’re spending it wisely on a product that serves them well for years, or even decades. That’s why we didn’t focus on price in our search for the best under-sink well water filters – we focused on overall value.
The under-sink water filters on this list are the best value for money systems you can buy today, offering exceptional features and performance aspects that make them well worth their price.
🧾 Buyer’s Guide
Under-sink well water filters are units that are designed to filter common well water contaminants and deliver filtered drinking water directly out of your faucet. These systems are hooked up to your cold water line and are powered by your home’s water pressure.
This section of the guide covers all the important information about buying a well water filter system for under your kitchen sink.
Types of Under-Sink Filter Systems for Well Water
There are three main types of under-sink water filtration systems for well water:
Single-stage water filtration systems consist of a single filter and are typically the cheapest and most compact options. Often, these filters combine more than one filtration process into a single cartridge. A carbon filter is usually the main media, and may be combined with sediment filter media, or specialized media, like KDF or activated alumina.
Multi-stage under-sink systems consist of two, three, four, or more stages. Usually, these filter stages include dedicated sediment and carbon filters, post or polishing filters, and specialized filters, like activated alumina. These filters offer more thorough, dedicated filtration, but they have a bigger effect on flow rate than single-stage units, and making filter replacements is more expensive. The installation and maintenance process tends to be a bit trickier with these systems, too.
Reverse osmosis (RO) under-sink systems are the best under-sink water treatment option for highly contaminated water. RO units combine a sediment and carbon filter with a semi-permeable membrane to remove virtually all contaminants from water, and often come with a separate faucet to prevent metal from leaching into the purified drinking water. The downside of RO is that you’ll need to pre-treat your well water supply with a sediment filter or a water softener to prevent damage to the RO membrane.
Pros and Cons of Under-sink Filtration Systems
Even the best under-sink water filters have their setbacks. Let’s look at the advantages and disadvantages of buying an under-counter water filter system to treat your well water:
- An under-counter water filtration system can remove an impressive host of harmful contaminants, from microbiological impurities to heavy metals.
- This type of water filter should noticeably improve the taste and smell of your tap water.
- If your home’s water pressure is adequate, an under-sink filter shouldn’t affect your flow rate.
- Under-sink systems are budget-friendly compared to whole-home water filters.
- Under-sink systems are more convenient than countertop filters because they provide filtered tap water on demand.
- Most under-sink systems are suitable for DIY installation.
- The filter capacity of an under-the-sink water filtration system is fairly limited. You’ll need to buy a filter replacement every 6-12 months.
- This type of filter only delivers filtered tap water via a single cold water feed line to one faucet.
- If your water pressure is low, you might need to install an electric pump before your filter to prevent it from reducing your flow rate.
- If your well water quality is poor, you might need a pre-treatment filter as well as an under-counter water filtration system.
Buying an Under-Sink Filtration System for Well Water: What to Consider
Here, you’ll learn about everything you should consider when buying an under-sink water filter system to treat your well water.
Your Water Quality & Pre-Treatment
Well water is rarely suitable for drinking without some form of treatment. It’s important to test your water annually to check for new contaminants, and treat your tap water accordingly.
The quality of your water will determine which under-sink filter system is best suited to your needs. For instance, if your water is prone to microbiological contamination, you’ll be best using a system that has a built-in UV filter. Or, if heavy metals are your biggest concern, look for a filter with a proven ability to remove iron, arsenic, lead, and so on.
Your water quality doesn’t only tell you what under-sink filter is best for you, but also gives you knowledge about whether you need a pre-filter. If your water has high sediment, dangerous pathogens, or hardness, you may need to install a sediment pre-filter, a UV purifier, or a water softener at your point of entry.
This is especially the case if you plan to buy a reverse osmosis system. No matter what your water quality, you need proper pre-treatment for an RO filter, and you should never use RO filters as a primary treatment for well water.
Your water parameters are also important to consider. If your water is too acidic (a common well water trait), it may spoil the filter media or cause the filter to be ineffective. In this case, pre-treatment is also recommended to alkalize your water.
Once you know what your water contains, your budget is the place to start.
Consider how much money you can afford to spend upfront on a water filter. If you can’t decide on a figure, a good rule is to ask yourself whether you could afford to pay for a system twice. If you couldn’t, your budget is probably too high.
You can find a highly capable under-sink well water filter for as little as $100, but the truly exceptional filters start at $500. Remember you’ll need to pay for annual maintenance, too, including the cost of replacement filters. Thankfully, this price is much cheaper, at about $100-$200 per year.
Learn all about the Average Cost for Installing an Under-Sink Water Filter 👈
Testing and Certifications
From a customer’s perspective, an official NSF certification is the best proof of a filter’s contaminant removal ability. The NSF is an independent testing and certification organization that all water filter manufacturers can use to test their products. NSF certifications to look for in under-sink filters for well water are:
- NSF 53, for contaminants with health effects, like lead, giardia, and VOCs.
- NSF 58, for reverse osmosis systems that can remove health-concerning contaminants.
- NSF Standard P231, for filters that can reduce microbiological contaminants, like viruses, cysts, and bacteria.
- NSF 401, for filters that can remove emerging contaminants, like pharmaceuticals, some pesticides, and chemicals like BPA.
Although NSF certifications are a mark of reassurance for customers, we wouldn’t recommend only looking at filters that are officially certified. This will narrow your choices massively because some manufacturers choose not to get their products certified by the NSF.
Instead, look at filters that have some form of proof of performance, such as an online datasheet displaying results from third-party testing.
Number of Filter Stages
Buying a multi-stage under-sink filter isn’t essential. However, the more stages your filtration system has, the more varied filter media the water will come into contact with, and the bigger the variety of contaminants that are removed.
Generally, multi-stage water filters are more expensive than a single-stage under-sink water filtration system. However, if you’re looking for quality output, we’d recommend a system with at least two separate stages.
There are a whole host of filtration processes that can be used in under-sink water filters. These include:
- Activated carbon/adsorption filtration, for improving water’s taste and odor
- RO membranes, which eliminate thousands of impurities
- UV light, which purifies water and kills microbiological contaminants
- Specialist resins and media, like activated alumina, KDF and ion exchange, which remove everything from heavy metals to fluoride, nitrite, and arsenic.
Different filtration methods remove different contaminants and have different lifespans. Ideally, find an under-sink water filter system that combines several of these methods to remove a broader range of impurities.
Flow Rate and Water Pressure
The flow rate and water pressure of a filter are a measure of the speed and output of water from the system. The better a system’s flow rate, the faster you’ll get access to filtered water.
Before installing a water filter system under your sink, your faucet should deliver a flow rate of about 1.5 to 2 gallons per minute. After installing a filtration system, your flow rate will likely drop to about 0.5 to 1.5 gallons per minute. The more stages the filter has, the slower the flow rate.
It’s common for water pressure to fluctuate in homes with private wells. Make sure your home has a water pressure of at least 60 PSI to deliver a strong enough flow of water to pass all the way through a multi-stage filtration system.
There’s no avoiding reduced flow rate from installing an under-sink water filter system, and as long as your water pressure is adequate, this shouldn’t be too disruptive.
On average, the filters in an under-sink filter system last for 6-24 months. The lifespans of the filters in your chosen system will affect how often you need to buy replacement filters.
If maintenance isn’t your thing, look for filters that last at least 12 months. It’s likely that you’ll need to pay more upfront for this privilege.
When you’re still comparing products, estimate how many filter replacements you’ll need to make per year, and the average cost of these replacements. It might be worth spending a bit more upfront on a filter that requires fewer filter changes, therefore costing less in the long run.
It’s important to carefully measure your available space and compare this to any water filter you plan to buy. The last thing you want is to have to send back a filter because it’s too tall or bulky to fit in your cabinet.
If you’re short of space, bulky tank-based reverse osmosis water filters are probably out of the question. Luckily, many under-sink water filters are designed to be as compact and space-saving as possible. Inline under-sink filters take up the least space.
Installation and Maintenance
Most under-sink water filters nowadays are advertised as being easy to install, even for people who don’t consider themselves DIY experts. But how true is this?
If you can follow detailed instructions and you have plenty of patience, you should be able to install any of the best under-sink water filters on this list.
When it comes to maintenance, most under-sink filter systems just need filter changes. The frequency of maintenance depends on the type of system you own, and how long the filters last. Look for filtration systems that are easy to maintain – you want filters that can be removed and replaced in a matter of minutes so you don’t end up dreading maintenance or putting it off for too long.

🧠 Best Under Sink Water Filter for Well Water FAQs
Is well water safe to drink?
Potentially – but even if your well water doesn’t contain pathogens that make you sick, it could still contain a host of other dangerous chemicals and heavy metals. That’s why it’s important to get your water tested at least once a year and treat it as necessary.
How do you purify well water for drinking?
The best way to purify well water for drinking is with a reverse osmosis unit – as long as it’s used downstream of a suitable pre-treatment system.
How do you make well water safe to drink?
To make sure your well water is safe to drink, you need either an under-sink filter or a whole house water filter with a UV light. This will kill pathogens in your water and make it suitable for drinking.
Are under-sink filters or whole-house water filters best?
It depends on what you’re looking for. If you just want to filter your drinking water, under-sink filters are easier to install and maintain, and more cost-effective, than a whole house filtration system. However, whole-house systems remove harmful contaminants from your entire home’s water supply, so you can drink, cook with, bathe in, and wash your clothes with filtered water.
Will an under-counter water filter resolve all my well water quality issues?
It depends. Even the best under-sink water filter might be incapable of thoroughly filtering your water if your TDS is high. You may need additional point of entry water treatment to remove pathogens, increase your water’s pH, soften your water, and remove high levels of iron.
